How do I know the Canon 6d shutter count via software, since it's not on the EXIF, and EOSInfo, gPhoto, MagicLantern don't work.
I have a 6d. Magic lantern shows me the shutter count. I dunno why you're not seeing it. It's on the menu with 0101 on it. Near the bottom. It displays two numbers separated with a +. The numbers before the + are photos taken. The numbers after the + are live view actuations.
Alternatively, you can use DSLR controller ($8 on Google Play) and that will also tell you the number of photos taken, but not the live view actuations.
have a nice day.
Unlike Nikon, Canon doesn't provide shutter actuation count in the EXIF data.
Canon 6D has a DIGIC 5+ processor, and unfortunately I can't say for sure if any of the mentioned application support Canon 6D or not.
EOScount says they can read information from some DIGIC 5 cameras, so I suggest you to try it.
Reading shutter count information is also possible at authorized Canon service centers.
The most obvious first thing to check is if your camera is set to continuous file naming or auto reset. If it is set to continuous file naming you likely can just look at your existing file names, such as IMG_5000.jpg or IMG_5000.CR2, then determine if you have more than one file on your computer with that name. If you only have one file with that name, you either deleted it or have only shot 5000 shots total.
Clearly this is not a definitive answer, but in many cases this will work. If you never changed this setting, saved most of your images, and are the first owner - this method works.
Many owners of DSLRs never take over 9,999 shots ever, believe it or not, so it is possible that you don't even need to have any saved files to determine shot count if it is under 10,000. Just take a new shot, look at the file name, and you have your shutter count.
ShutterCount for Mac. It is certified to work with the Canon 6D. https://itunes.apple.com/us/app/shuttercount/id720123827?mt=12 Dave
